Isabella says she is "gratified" by her husband's sadness. If we recall the early chapters of the book, Isabella was girlish and shy. She would blush and run away at the mention of Heathcliff's name. When the chance came for her to get her knight in shining armor, she took it, not realizing that she had created a Heathcliff in her head that was much different from the reality. Silly mistakes made in youth, at a time of critical development, can echo throughout one's life. In Isabella's case, this cost her her empathy. This hardened Isabella is hardly recognizable from the girl at the beginning of the book. In these passages, we see her showing signs of having been poisoned by the pattern of cruelty displayed by the Earnshaws and Heathcliff. Interestingly, it seems to be her personal strength that caused her to take on this defense mechanism, as Edgar, a much softer character, never did exhibit such behavior despite his time spent with Catherine. This raises a question: who is the happier sibling? Isabella, battle-hardened and bitter, or Edgar, abused but with his humanity fully intact?
